I normally run a 315/60 M/T Drag Radial and the track that I a running at now ( Because the rest are closed)I can't hook with the radials. I put my 29.5/10.5 W's on it and it hooks great but it goes straight to the right when I leave the line. I checked the tire diameter and they are with in a 1/4 in. I switched sides with the tires and it still goes to the right. The rear suspension is Caltrac bars with stock leaf springs. Why would it go straight with the radials and go to the right so bad that I have to let off the gas or it will hit the tree or wall if I stay in it. It snatches the front tires straight up and goes to the right.
